has it been difficult to sight in ?

(i figure the alignment can be adjusted with little set screws...  or do you just get a feel for the position of the light versus actual point lens covers..?)

I haven't sighted it in properly yet. It appears to converge too close, so I will have to raise the sight to be about parallel. I think I will only have to do this once. I will be happy if the center of the sensor always points about 4" below the dot. I don't think I will need to take into account different distances.

There are screws that are adjusted by Allen keys. But the fitting into the hot shoe has sideways slack in it before it is tightened up, and I think it will have to be re-sighted horizontally each time it is fitted to the camera.

I'll give more information when I've had some field experience.
